[Introduction]：E35-2G4T10S is a new generation of 2.4GHz wireless serial port module designed based on Telink's TLSR8208 chip solution. It has multiple transmission modes, works in the 2400~2480MHz frequency band, uses standard stamp hole patch packaging, and has a UART communication interface, which is convenient for users to develop and use. The E35-2G4T10S series is an ISM band wireless data transmission module; it supports wireless transparent transmission, fixed-point transmission, broadcast transmission, serial port upgrade, communication encryption and other functions, and can provide customized development services.
